"These cute little young lego action figure set comes with 440 pieces. It was a little challenging to build since it does come with so many small pieces. The set comes with Batman, Robin, The Joker, & Harley Quinn mini figures along with a Batmobile and motorcycle that you have to built. Building the set was so much fun! The pieces are very small, but very sturdy, and durable. The best part is that you can seat both the Joker and Harley Quinn on the trike."
